BP’s Greater Tortue Ahmeyim FLNG project located offshore Mauritania and Senegal continues to progress towards the start of production next year.
France’s Eiffage Genie Civil said in a statement on Wednesday it had finished the central platform of the hub located 10 km from the coast on the Mauritania-Senegal border.
This platform represents more than 3200 tonnes of steel structure and 200 prefabricated concrete elements installed by two 300-tonne cranes moving forward, according to Eiffage.
The firm said that it supplied all these elements by cargo barges from its marine base in the port of Dakar.
In addition, a fleet of fifteen vessels was operated by Eiffage Genie Civil Marine teams, including a 300-bed floatel.
“Close management of simultaneous operations with our partner Saipem ensured safety and adherence to the schedule,” the firm said.
Eiffage and Italy’s Saipem won the contract from BP for the Tortue development back in 2019.
The hub includes the berthing facilities for the FLNG and the breakwater.
Earlier this year, Eiffage completed the construction of 21 mega caissons at its Dakar site in Senegal.
These caissons constitute the breakwater that would protect the project’s FLNG and LNG carriers offshore the coast of Saint-Louis.
Gimi FLNG conversion
According to BP, the Tortue/Ahmeyim gas field, located offshore on the border between Mauritania and Senegal, has about 15 trillion cubic feet of gas.
The project’s FPSO will process the gas, removing heavier hydrocarbon components, prior to delivering it to the floating LNG provider which will be located at the hub.
Singapore’s Keppel shipyard is currently converting Golar’s Gimi FLNG for the project.
Golar said in May the FLNG was 83 percent technically complete. The yard should deliver the unit in the first half of the next year.
Once deployed offshore Mauritania and Senegal, it would provide about 2.5 million tonnes of LNG per annum on average.
Besides operator BP, the project includes Kosmos Energy and national oil companies Petrosen and SMHPM.
